What is aortic valve
What is the narrowing of the aortic valve (aortic stenosis)?
Aortic valve is the heart valve between the main artery (aorta) and left ventricle. It usually consists of three "seal" to prevent blood from flowing back to the heart when the hearts pumping phase is over. Constriction of the aortic valve, aortic stenosis, a condition that prevents blood flow between the left ventricle and aorta. Narrowing can sit in the flap, the flap or flap. To squeeze out blood from the heart through a narrow aortic valve, increasing the load of the heart. In time, it may cause serious abrasion injuries at heart.
Constriction of the aortic valve is the most common acquired valve disease. It acquired means that the condition is congenital. The condition is most collective after 70 years, and is 3-4 times more common in men. 25-35% of people over 65-70 years have evidence of narrowing of the aortic valve on the ultrasound, but only 2-3% of these have affected the blood circulation as a result of the narrow area.
What causes narrowing of the aortic valve?
A narrowing of the aortic valve until the age of 70 will often result that the flap has only two seals rather than three seals as is the norm. This makes the valve more susceptible to lime swoop. After the age of 70 will also find chalk catchment in valves that have a normal number of seals. Rheumatic fever (inflammation of the joints, heart and general infection with fever) is now a rare cause narrowing of the aortic valve.
